When I run the following Maple codes, for some reason I get an error:


> restart:with(DEtools):with(plots):

> ode:= diff(p(t), t) = r*(1.5-sin(2*t))*p(t);

> odePlot := DEplot(ode, P(t), t = -3 .. 3, P = 0 .. 1000);

Error, (in DEtools/DEplot/CheckDE) derivatives must be given explicitly


I'm not sure what it's talking about? I feel like I've done things like this many times in the past. Any help...
